(Binary Method + Extra Shortcuts)

Subnetting Best Method is Binary Method + Extra Shortcuts which involves stealing /taking away bits from the Host Portion & allocating those stolen bits to the Network portion thereby creating a New Address

1. When asked to workout the Number of Hosts per Subnet:

Hosts/Subnet = 2^n -2 (-2 for Subnet & Broadcast Address)

(count bits from Right to Left)

2. When asked to workout the Number of Networks:

Networks = 2^n

(count bits from Left to Right)

Practical Example:
